WTT :- Working Time Table. Used for departmental purposes, internal workings like watering timing, parceling, locomotive change, crew change etc are taken care of here. Not available for general public.
PTT :- Public/Passenger Time Table. Made available for the passengers . A train will not depart a said station before the PTT, for example take this train for instance. The train is given a 1 hrs plus between BKSC and RJB block hut. So even the train reaches RJB much before time, it won't depart until the scheduled departure timings even though RJB isn't the best of places for an express train to be standing late at night. The train may depart later but never before the scheduled departure timings.
WTT...
more... and PTT may or may not be the same.
Example you will see that in some stations where a said train undergoes a rake reversal, a halt timings of 5 or 10 minutes are provided in the PTT. The WTT of such trains are likely different from the PTT.
Some one please do correct me if I am wrong here.
please wait...Translate to EnglishYo, check it - Working Time Table (WTT) is all about handling internal stuff like train schedules, crew changes, and all that jive. It ain't for the public eye, nah mean? On the flip side, Public/Passenger Time Table (PTT) is for us regular folks. It shows when the trains dip out and stuff. So, like, even if a train rolls up to a spot early, it's gotta wait until its scheduled PTT to bounce. You feel me? WTT and PTT ain't always the same deal, yo. For example, sometimes PTT might show a train chillin' longer at a spot for passenger swap, but in the WTT it's all different. So yeah, if I'm off base, someone holla at your girl and set the record straight. Peace!
